How to change element title inside UITableViewCell?

Question

I have a button on custom tableviewcell. I've been able add action to this button by add target like below code:

    var playButton = cell.contentView.viewWithTag(5) as? UIButton
    var sender : UIButton = UIButton()
    playButton?.addTarget(self, action: "playPost:", forControlEvents: UIControlEvents.TouchUpInside)
    playButton?.layer.setValue(object["previewUrl"] as? String, forKey: "songUrl")
    playButton?.layer.setValue(indexPath.row, forKey: "index")

But, how can I change it's title whenever I clicked this button?

If your function is playPost(), you could change the value passed in (which is the sender of the function, by default) like this:

func playPost(sender: UIButton) {

    sender.setTitle("New title", forState: UIControlState.Normal);
}

thank you very much, this is what I looking for. Is it possible to change other element title on the same cell? – Ega Setya Putra Jun 17 '15 at 04:59
@EgaSetyaPutra Yes you could. I'd set the `tag` of the button to the cell's `row`, then call `cellForRowAtIndexPath:`, constructing the index path using the button's tag. Make sense? – rebello95 Jun 17 '15 at 05:03
I don't get it, could you give some reference or code snippet? – Ega Setya Putra Jun 17 '15 at 05:08

You can Change UIButton title by using setTitle Method

Example

    var button = UIButton(frame: CGRect(x: 50, y: 50, width: 200, height: 100))
    button.backgroundColor = UIColor.blackColor()
    button.setTitle("Start", forState: UIControlState.Normal)
    button.addTarget(self, action: "pressButton:", forControlEvents: UIControlEvents.TouchUpInside)
    self.view.addSubview(button)


   func pressButton(sender:UIButton)
   {
      if sender.titleLabel?.text == "Start"
      {
        sender.setTitle("Stop", forState: UIControlState.Normal)
      }
      else
      {
        sender.setTitle("Start", forState: UIControlState.Normal)
      }
   }
